ANIMAL-STANCHION.

Specification of Le-tterslatent.

Patented July'29, 1919.

Application filed April 1:9, 1918. Serial N 0. 229,597.

To all whom it may concern:

Be it known that I, JOHN M. B. LEWIS, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Animal-Stanchions, of which the following is a speci fication.

.My invention relates to improvements in animal stancliions.

An importantob'jcct of the invention is to provide simple and reliable means to hold or look the stanchion against turning move ment upon its vertical axis, when it is opened, but allowing of the free turning movement of the stanchion upon its vertical axis, when it is closed.

A further object of the invention is to provide a stanchion of the above mentioned character, so constructed that the opposite sides thereof open in opposite directions, thus suitably closing the spaces inthe stall upon opposite sides of the stanchion, and dispensing with the employment of the ordinary, stop rod or element ordinarily used in connection with the stanchion which opens at one side only.

A further object of the invention is to provide a stanchion of the above .mentioned character, having means for properly retaining the same in position, but allowing of substantial movements thereof in alldirections for the convenience of the animal, while standing or lying down.

A further object of the invention is to provide flexible connections for retaining the stanchion in the desired position, while in the opened or closed condition, which connections are adjustable to throw the stanchion forwardly or rearwardly.

Other objects and advantages of the invention will .be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed ,to designate like parts throughout the same,

Figure 1 is a perspective view of a Stan-- chion embodying my invention, showing the same locked in the closed position, and in use in a stall,

Fig. 2 is a perspective view of the stanchion, in the open position,

Fig. 3 is a plan view of the attaching-elements, the stanchion being omitted,

Fig. 4 is a central vertical sectional view through a supporting rod and associated elements, parts being shown in elevation,

Fig. 5 is a detail section through a pivotal connection between the stanchion arms and anchor member,

Fig. 6 is a side elevation of the pivoted ends of the upper and lower arms constituting one side of the stanchion.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10' designates the floor of :1. stall, having a curb 11, forwardly of which is arranged a manger 12 for receiving the feed.

The numeral 13 designates vertical posts or pipes, secured at their lower ends to the curb 11. At their upper ends the posts 13 are connected through the medium of T- couplings 14, with a horizontal pipe or sup port 15;.

The numeral 16 designates stall partitions which may be formed of longitudinally curved pipes, the lower ends of which are secured to the floor 10 and the upper ends to the posts or pipes 13 by means of conplings 17. i

The stall hereinbefore described is of the well known construction and forms no part ofthe present invention but is shown for the purpose of more fully explaining the of which are adapted to open outwardly;

Each side member 18 embodies upper and lower arms or sections 19 and 20. The lower ends of the arms 19 are preferably provided with a pair of spaced apertured knuckles 21, receiving apertured knuckles 22, formed upon the upper ends of the arms 20. The knuckles 21 and 22 are pivotally connected by pins 23 or the like. It is thus apparent that these apertured knuckles afford hinge connections between the arms 19 and 20, which allow the same to swing transversely of the stall but positively prevent the arms from swinging at a right angle to this direction. Any other suitable means may be employed for effecting this hinge connection.

Means are provided to lock the arms 19 and 20 together, preferably at 'a point near their hinged connections, such means comprising sliding bolts 24, operating within guide lugs 25, secured to the arms 19. The

bolts 25 are moved downwardly by springs 26. The lower ends of the bolts are adapted for insertion within sockets 27 rigidly secured to the upper portions of the arms 20. The upper ends of the bolts preferably carry rings 28 or the like so that the bolts may be conveniently elevated. It is thus seen that when the bolts 24 are inserted within the sockets 27 they will serve to rigidly connect the arms 19 and 20 thereby positively preventing the same from swinging upon their hinged connection.

At their upper ends, one arm 19 carries a pair of spaced knuckles 29 for receiving therebetween a knuckle 30 carried by the other arm 19. These knuckles are pivotally connected by means of a pin 31, passing through openings in the forked head 32 se cured to the lower end of an attaching element or rod 33. It is thus apparent that the upper ends of the arms 19 are pivotally connected with the attaching rod 33 and are adapted to be swung laterally in the plane of the stanchion, as clearly illustrated in Fig. 2. The attaching element or rod 33 is provided upon one side with a longitudinally extending key or rib 34, having a lower end 35 spaced a substantial distance from the lower end thereof or from the forked head 32. The attaching element or rod 33 is adapted for insertion through a socket 36, having a main circular opening or bore 37 and a slot 39, at one side thereof, for receiving the key 34. The socket 36 is carried by a rod 39, adapted for insertion within the transverse tubular element of a cross-coupling 40, and detachably clamped therein by a bolt 41. The rod 39 has a plurality of openings 42 formed therein, for receiving the bolt 41, whereby the rod 39 may be longitudinally adjusted. If desired, the rod 39 may be withdrawn from the rear end of the cross-coupling 40 and inserted into the opposite or forward end thereof for a purpose to be more fully described.

As more clearly shown in Figs. 2 and 4 the numeral 43 designates a latch or look element, pivoted to the rod 39, as shown at 44. This latch element is provided at its forward end with a head 45, adapted when in the lower position, to be disposed beneath the lower end 35 of the key 34, thereby positively locking the attaching element or rod 33 against downward movement. This latch or lock element 43 is preferably em ployed in connection with the bolts 24, while these bolts may be dispensed with and the element 43 employed alone with some degree of success.

One arm 20 is provided at its lower end.

through the sides of a U-shaped socket 48, receiving these apertured knuckles. This U-shaped socket is provided in its bottom or transverse member 49 with an opening, pivotally receiving the shank of an eye-bolt 50 which is swiveled therein. The eye-bolt 50 is preferably horizontally elongated and receives a similar eye-bolt 51, in interlocking engagement therewith. The eye-bolt 51 has a shank 52.

The numeral 53 designates adjustable attaching links, provided at corresponding ends with apertured heads 54, the shank 52 extending through the apertures of these heads to be swiveled therein, the shank carrying a nut -55 at its lower end. The links 53 are provided with a plurality of spaced apertures 56, adapted for receiving anchor bolts 57, preferably secured within the curb 11. It is thus apparent that these anchor bolts may be inserted in a selected pair of the openings 56, thereby throwing the connecting links rearwardly or forwardly, and as indicated in dotted lines,

these connecting links may be reversed so that their apertured heads 54 will extend forwardly of the curb instead of rearwardly. The function of this construction is to provide means to forwardly and rearwardly adjust the point of connection of the lower portion or end of the stanchion, as will be found advantageous, in connection with cows of different lengths. The rod 39 is adjustable forwardly and rearwardly, as above stated, so that the point of support of the upper end of the stanchion may be correspondingly adjusted forwardly and rearwardly, and when the links 53 are extended forwardly instead of rearwardly the rod 39 is inserted in the forward end of the crosscoupling 40 instead of the rear end.

In the use of the apparatus, when the stanchion is in the closed position, as illus trated in Fig. 1, the attaching element or bolt 33 is elevated, and the key 34 is arranged wholly above the socket 36, and out of the slot 38. It is therefore apparent that the stanchion is free to turn upon its vertical axis, the eye-bolts 50 and 51 also allowing of this swinging or turning movement, besides allowing the lower end of the stanchion to partake of substantial movements in all directions. The movements of the stanchion in all directions, are permitted by the swinging movements of the attaching element or rod 33 in the opening 37, which is tapered and increases .in diameter downwardly. When the stanchion is in the closed position, the locking element or latch 43 is disposed beneath the lower end 35 of the key 34, and the bolts 24 are inserted within the sockets 27, whereby the arms 19 and 20 are securely locked together and against outward or spreading movement. 7 V I To open the stanchion, the same is first other.

slightly elevated, to allow the element 43 being swung to the upper position, and upon the slight downward movement of the stanchion this element will contact with the side of the rib or key 34. The bolts 24 are now moved upwardly and withdrawn from the sockets 27, at which time the opposite side members of the stanchion are adapted to be moved outwardly or away from each As both side members 18 move outwardly it is obvious that the open stanchion will sufiiciently close the opening or space between the vertical post 13, whereby the stop A, shown in dotted lines, and employed with stanchions opening on side only, may be dispensed with.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
